Definitions

  • the invention relates to a power transmission belt made of elastomeric material with a tension member layer embedded in the elastic belt body and with a friction-reducing design that promotes the sliding properties.
  • Elastomeric power transmission belts or drive belts such as V-belts, V-ribbed belts or rubber toothed belts, have a vulcanized or hardened belt body. They are subject to different requirements.
  • the motion-transmitting belt surfaces interacting with the pulleys are subject to high mechanical stress. This stress leads to abrasion or wear that affects the life of the belt.
  • the outer surfaces of the belt are exposed to chemical attacks due to weather and operating media influences.
  • the power transmission belt should preferably not lose its specific properties, such as its elastic behavior, even at low and high temperatures. Furthermore, the Belt body embrittlement of the rubber components in the course of its operating time, because plasticizer components diffuse out and attack embrittlement-promoting substances such as ozone.
  • Another product requirement for the power transmission belt is the increasingly important requirement for a particularly low noise level of the belt drive.
  • the reduction in the running noise of the power transmission belt in the pulleys should be achieved particularly in the automotive and household goods industries.
  • a power transmission belt designed as a V-belt which has a horizontal, centrally arranged rubber layer in which an anti-friction material in the form of graphite is homogeneously distributed.
  • This training a high dimensional stability of the belt is to be achieved.
  • the movement-transmitting outer surfaces of the V-belt have a lower coefficient of friction, but alternating with areas of higher coefficients of friction when viewed over the side surface. This training does not meet the above requirements.
  • V-belt From DE-B-27 26 904 an endless V-belt is known in which homogeneously distributed anti-friction material is present.
  • the belt body consists of an elastomeric compound with a polymer and 15 to 90 Parts by weight of graphite per 100 parts by weight of polymer.
  • the side walls of the V-belt should have a significantly reduced coefficient of friction. This can reduce the frictional forces and thus the heat generated by the belt. As a result of the reduced overall belt tension, the wear is said to be smaller and the service life to be positively influenced.
  • V-belt which is provided with organic reinforcing fibers and contains a friction regulating agent which consists of a polytetrafluoroethylene powder.
  • the incorporation of anti-friction material into the full V-belt body has the disadvantage that the movement-transmitting belt surfaces are not closed surfaces. During operation, individual material particles are removed and represent defects that offer points of attack for embrittlement and abrasion.
  • the integration of the anti-friction material in the material of the belt body has the character of the integration of a filler. With a high concentration of this filler, the elastomer properties of the belt body change in an unfavorable manner. With a lower concentration of the filler, the friction-reducing effect is only very slight.
  • the anti-friction agent is subject to permanent consumption due to operational wear, because it has no firm adhesion to structural surfaces.
  • the invention has for its object to provide a power transmission belt of the type described, which has a reduced coefficient of friction, without its elastic properties change, and which achieves a low noise level with a long service life.
  • the object is achieved in that at least the wear-dependent, motion-transmitting surfaces of the power transmission belt have a coating which is crosslinked to the belt surface by means of a polymer matrix containing fluorine-containing plastic, the fluorine-containing plastic being boundless in the polymer matrix.
  • Fluorine-containing plastics have particularly good sliding properties.
  • the best known fluorine-containing plastic polytetrafluoroethylene (PTFE)
  • PTFE polytetrafluoroethylene
  • PTFE polytetrafluoroethylene
  • the coating containing polytetrafluoroethylene is very good, although normally polytetrafluoroethylene would adhere poorly to the elastomeric base body.
  • the application in a crosslinkable, polymer-containing matrix overcomes this poor adhesion property.
  • the coated surface is protected against chemical attacks. Abrasion is significantly reduced.
  • the coating according to the invention remains elastic over a long service life and does not harden even in long-term operation. This prevents the belt body from cracking or cracking. Due to the fluoroplastic-containing coating, the coated belt surface is virtually sealed, which also reduces the evaporation of plasticizer components. This has the advantageous consequence that embrittlement of the rubber of the Belt body is prevented, which is also supported by the exclusion of embrittlement-promoting substances such as ozone.
  • the belt properties remain in their original values over a longer period of operation.
  • An advantageous embodiment of the invention is characterized in claim 2.
  • a power transmission belt with rubber reinforcement fabrics arranged on the outer surfaces on the one hand a certain noise reduction and on the other hand an area with a lower coefficient of friction is achieved.
  • the motion-transmitting belt surfaces are protected from premature wear.
  • the fabric reinforces the tooth contour so that the teeth are not sheared off.
  • the outside of the rubberized reinforcing fabric is coated with a cross-linked, polymer-containing matrix that contains a fluorine-containing plastic. The polymer matrix is securely bonded to the rubberized outer surface of the reinforcement fabric without any visible boundary layer formation and cannot shear off in continuous mechanical operation. Signs of detachment of e.g. A PTFE-containing coating cannot be observed.
  • the fluorine-containing plastic is polytetrafluoroethylene.
  • the belt surfaces provided with the coating are flocked with short fibers. From DE-B-22 11 278 it is known to let fibers protrude beyond the movement-transmitting surfaces of a drive belt. But this is in full Driving belt body embedded fiber inlays.
  • the flocked fibers are attached to the belt body via the polymer matrix and are not in the full elastomer belt body, which would mean a change in the elastic behavior. There are no negative changes in the properties of the belt body due to the fiber flocking.
  • the surface fibers are in a homogeneous distribution. The formation of fiber nests is prevented.
  • the fluoroplastic-containing coating contains a filler made of a material with a damping effect. This design reduces sudden loads on the belt drive and improves synchronism.
  • the coating has an addition of conductive carbon black components.
  • the coating thus forms an electrically conductive surface, which prevents electrostatic charging of the belt body.
  • the invention provides a power transmission belt which is provided with a friction-reducing coating, which has a material connection with the rubber body of the power transmission belt by crosslinking.
  • the invention also relates to a method for producing a power transmission belt according to claim 1. It is characterized in that at least on the motion-transmitting surfaces of the power transmission belt, a liquid polymer matrix containing a fluoroplastic, such as PTFE, which contains crosslinkable constituents, is applied, and in that the Is dried polymer matrix and thereby undergoes a crosslinking process for binding with the elastomeric belt body.
  • a fluoroplastic such as PTFE
  • a coating composition based on tetrafluoroethylene and in the form of a dispersion can be used to produce the coating.
  • the liquid polymer matrix is applied to one or more belt surfaces by spraying or brushing in a suitable thickness of, for example, 50 ⁇ . It penetrates the surface of the belt body and connects there during crosslinking or polymerisation without forming an interface. The result is a protected belt surface that is virtually sealed, but still does not adversely affect the elastic behavior in the connection area.
  • the liquid polymer matrix is applied before the belt body is vulcanized.
  • the subsequent joint heating or vulcanization of the polymer matrix and belt body results in a shape-accurate, uniform and contoured shape of the coating on the belt body.
  • a high adhesive force is achieved due to the co-vulcanization of the coating and belt body.
  • the elastic properties of the belt body are inevitably transferred to the coating.
  • the technical outlay in the production of a power transmission belt according to the invention is reduced because curing or crosslinking of the coating and vulcanization of the belt body are carried out in a single process step.
  • the coated surfaces of the power transmission belt are under flocked with short fibers.
  • the short fibers are introduced into the not yet dried or cross-linked polymer matrix and aligned by the electrostatic action. The following drying process fixes the flocked fibers.
  • the invention creates a power transmission belt, the belt-specific properties of which remain in their original values longer. If the procedural coating is applied to all belt surfaces, the belt body is completely sealed. This makes it possible to choose a lower elastomer quality for the belt body, since the sealing with the PTFE-containing polymer matrix is a refinement and a protection against an early disadvantageous change in the belt properties.
  • the V-belt shown in FIG. 1 has a coating 12 of a cross-linked, PTFE-containing polymer matrix on its load-bearing flanks 11.
  • the polymer matrix has formed a cross-linked bond with the surfaces of the flanks 11, with no pronounced boundary layer formation being present. With 14 inextensible tension cords are designated.
  • the basic body of the V-belts are made of CR rubber (polychloroprene rubber).
  • the rubber toothed belt shown in FIG. 2 has a firmly applied, rubberized reinforcing fabric 22 on its molded face 21 which has teeth 21.
  • This rubberized reinforcing fabric 22 is made of polyamide.
  • the outer surface of the reinforcing fabric 22 is provided with a coating 12 made of a cross-linked polymer matrix that contains 20% PTFE.
  • the rest are monomeric or oligomeric polymer building blocks, for example based on isocyanate.
  • the PTFE coating 12 carries outward, flocked fibers 23, which further increase the quiet running of the belt drive.
  • the rubber timing belt shown in Fig. 3 is also equipped with a rubberized reinforcing fabric 22 on the running side provided with teeth 21.
  • the coating 32 with the polymer-containing matrix is significantly thicker in this embodiment since it contains fillers 33 which have a damping effect.
  • Suitable fillers 33 are rubber powder, fibers, graphite, polyamide powder and the like.
  • the movement-transmitting belt surfaces are each coated with a crosslinked polymer matrix containing PTFE.
  • the liquid polymer matrix containing 20% PTFE which contains monomeric or oligomeric polymer building blocks based on isocyanate in a solvent, is applied to the belt surfaces sprayed on and subjected to a drying process in which the polymer matrix crosslinks on the belt surface.
  • the elastomeric underlay, the belt body is crosslinked, which results in a cohesive connection of the coating without any detectable boundary layer formation.
